Abstract:

A research was conducted to analyze agroecologycal characteristic of agroforestry system in Cianjur Watershed landscape. Observation and interviews were held to 30 samples of agroforestry field and respondents in the upper stream, the middle stream and the down stream of Cianjur Watershed, respectively. The results showed, that the communities in the three zones of Cianjur Watershed have been conducting agroforestry practice in order to manage their dry land. It’s found the differences characteristic of agroforestry system between the upper stream and the down stream. In the upper stream, agroforestry practices were found in a forest garden. This area is the buffer zone of Gede Pangrango Mountain. In the upper stream, the number of trees found 5 species and 12 species of plants. In the middle stream area, agroforestry practices were found in community lands and the tea estate plantation. In the community lands the number of trees found 20 species and 12 species of plant. In the down stream area, agroforestry were practiced in community lands and the flat area. The number of trees is 23 species and 11 species of plants. The middle stream agroforestry system characteristic was known as a transition condition between the upper and the down streams. The characteristic of biophisic and agroclimate have affected to total individual number and species of trees and cash crop. Planting index of cash crops is 2.93, 2.53 and 1.43 in the upper, middle and down stream, respectively. The average annual income from cash crops in the three zones are 15.866.250, 4.771.643 and 735.918 (IDR/ha/yr) from the upper, the middle to the down streams, respectively. The productivity of cash crops in the three zones of Cianjur watershed area, in the generally also lower than the potential yield and data from Cianjur Agriculture Official 2009. Furthermore, the dominant cash crops in the upper stream are carrot, cabbage, tomato, scallion, mustard and chili. In the middle stream are corn, chili, tomato, carrot, and mustard, and than in the down stream are corn, chili, tomato and cassava.The aspects of sustainability can be seen from the B/C ratio, where B/C ratio in the three zones of watersheds Cianjur worth more than 1. The B/C ratio in the upper stream 1:09, in the middle stream 2.89 and the downstream 1:02. The sustainability of agroforestry systems in every zone, was defined for aspects of productivity, economic, social and culture and ecologycal. For the aspect of environmental sustainability, in the upper stream more lower than in the middle and the down stream.The aspects of the use of chemical fertilizers and pesticides, in the downstream is lowest of use of fertilizers and chemical pesticides for the management of agroforestry systems. There are differences of sustainability indexs in the three zones area in ianjur watershed. The average of indexs sustainability is 12.12 (moderat suatainability).in scale 11-15
